A nimble, four-legged robot is so surefooted it can recover its balance even after being given a hefty kick. The machine, which moves like a cross between a goat and a pantomime horse, is being developed as a robotic pack mule for the US military.
BigDog is described by its developers Boston Dynamics as "the most advanced quadruped robot on Earth". The company have released a new video of the robot negotiating steep slopes, crossing rocky ground and dealing with the sharp kick.
